我有一个对话框/模式,我需要沿其宽度匹配父对象。然而,它一直在做包装内容。有没有办法纠正这个问题

这是我的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/my_root"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:background="#55555555" >

        <Button
            android:id="@+id/dogs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            android:background="#AAAAAA"
            android:clickable="true"
            android:gravity="center"
            android:onClick="onDogsClicked"
            android:text="Dogs" />

        <Button
            android:id="@+id/cats"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            android:background="#AAAAAA"
            android:clickable="true"
            android:gravity="center"
            android:onClick="Cats"
            android:text="Cat" />

        <Button
            android:id="@+id/snake"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            android:background="#FF0000"
            android:clickable="true"
            android:gravity="center"
            android:onClick="onSnakeClicked"
            android:text="Snake" />

        <Button
            android:id="@+id/sheep"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            android:background="#AAAAAA"
            android:clickable="true"
            android:gravity="center"
            android:onClick="onSheepClicked"
            android:text="Sheep" />
    </LinearLayout>

</LinearLayout>

我也有同样的问题,我找不到在XML中实现它的解决方案。但是在.java文件中有一个解决方案

    WindowManager.LayoutParams params = animalsView.getWindow().getAttributes();
    params.gravity = Gravity.BOTTOM;
    params.height = 100;
    params.width = android.view.ViewGroup.LayoutParams.MATCH_PARENT;
试试这个

public void onAnimalsClicked(View v) {

    LayoutInflater inflater = getLayoutInflater();
    View dialoglayout = inflater.inflate(R.layout.animals_layout,
        (ViewGroup) findViewById(R.id.my_root));

    animalsView = new Dialog(this, R.style.CustomDialog);

    ........

    animalsView.setContentView(dialoglayout);

    animalsView.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);

    ......

    animalsView.show();
}

我想你应该试试这个。当我面对这个问题时,我正在使用覆盖层。希望这对你有帮助

 Dialog animalsView;

    public void onAnimalsClicked(View v) {

        LayoutInflater inflater = getLayoutInflater();
        View dialoglayout = inflater.inflate(R.layout.animals_layout,
            (ViewGroup) findViewById(R.id.my_root));

        animalsView = new Dialog(this, R.style.CustomDialog);
        WindowManager.LayoutParams wmlp = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.MATCH_PARENT,
                WindowManager.LayoutParams.MATCH_PARENT, 
                WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
                        WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
                PixelFormat.TRANSPARENT);

        wmlp.gravity = Gravity.BOTTOM;
        wmlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
        animalsView.getWindow().setAttributes(wmlp);

        animalsView.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        animalsView.setContentView(dialoglayout);
        animalsView.getWindow().setBackgroundDrawable(new ColorDrawable(0));
        animalsView.show();
    }

得到了类似的问题,并通过了大量关于此问题的StackOverflow帖子

我尝试了所有可能的解决方案(主要是以所有可能的方式更改对话框窗口的布局配置),但没有一个有效

然而,当比较
match_parent
工作的对话框的XML布局和它不工作的对话框的XML布局时,我最终发现了一种奇怪的方法使其工作:

我必须将对话框的
layout\u height
设置为
match\u parent
,如下所示:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:padding="@dimen/activity_horizontal_margin"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    // ...

</LinearLayout>

我现在也面临同样的问题。你能找到解决办法吗?
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:padding="@dimen/activity_horizontal_margin"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    // ...

</LinearLayout>
    final Dialog dialogLayout = new Dialog(mContext);
    dialogLayout.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialogLayout.setCancelable(false);

    View layout = mContext.getLayoutInflater().inflate(R.layout.popup_dialog_introduce_myself, null);
    dialogLayout.setContentView(layout);
    //  ...
    dialogLayout.show();
